Instead of changing colors globally, you can map variables to colors – in other words, make the color conditional on a variable, by putting it inside an aes() statement. # Bars: x and fill both depend on cond2 ggplot(df, aes(x=cond, y=yval, fill=cond)) + geom_bar(stat="identit...
geom_raster creates a coloured heatmap, with two variables acting as the x- and y-coordinates and a third variable mapping onto a colour. (It is coded similarly to geom_tile and is generated more quickly.) This uses the volcano dataset that comes pre-loaded with R. library(reshape2) lib...

Aestheticsis used to indicate x and y variables. It can also be used to control thecolor, thesizeor theshapeof points, the height of bars, etc….. Geometrydefines the type of graphics (histogram,box plot,line plot,density plot,dot plot, ….) ...

While scatter plot lets you compare the relationship between 2 continuous variables, a bubble chart serves well if you want to understand relationship within the underlying groups based on: A Categorical variable (by changing the color) and Another continuous variable (by changing the size of points...

对于折线图, 可以在geom_line()函数中用color参数指定颜色, 用linetype参数指定线型, 用size参数指定以毫米为单位的粗细。 线型包括: 0:不画线; 1:实线; 2:dashed; 3:dotted; 4:dotdash; 5:longdash; 6:twodash。 30.4.1.1 找出期望寿命增长不稳定的国家 ...
